Fix ci-bonsai-daily BDD: OperatorSpy.bl_rna + stale MEP port name

Two independent test-harness/fixture defects in test/bim/test_feature.py:

- OperatorSpy had no bl_rna, so any BDD step that redraws a panel calling
  helper.draw_filter() (which tests "module" in op.bl_rna.properties)
  crashed with AttributeError. Give OperatorSpy a bl_rna property that
  forwards to the real registered operator class
  (bpy.types[bl_idname].bl_rna), matching live UILayout.operator()
  semantics. Fixes test_select_all_walls and test_edit_filter_query.
- The shared "I create default MEP types" step looked up
  bpy.data.objects["IfcDistributionPort/Port"], but port creation never
  sets port.Name, so tool.Loader.get_name deterministically names the
  object "IfcDistributionPort/Unnamed". Update the literal. Fixes the MEP
  scenarios (connect/transition/bend) that share this setup.

Verified in headless Blender: OperatorSpy scenarios 2 passed (were
AttributeError); MEP test_connect_mep_elements* go from
KeyError 'IfcDistributionPort/Port' to passing.

This change was made with the assistance of an AI tool.
